 |

What is PyMenu?
PyMenu is a replacement for the standard menu that you get when you right click on the root window in minimalist window managers. It is written in 100% Python and uses the PyGTK and pyxdg libraries. I wrote it because I wanted to learn PyGTK, become more familiar with Python itself, and because I thought specifying the icons I wanted by hand sucked 
What makes PyMenu special?
The two main reasons I wanted PyMenu was that I thought it was silly that all the WM's were running around with their own obscure formats for making menus. I just wanted to make a folder with symlinks in it, and have it be treated as a menu -- a feature PyMenu supports. Also, PyMenu searches for icons automatically, so you don't have to tell your WM that yes, surprise, you want firefox.png to be the icon for firefox. All features:
-Can make menus out of folders of symlinks
-Support for the freedesktop.org .desktop file format
-Configure with python instead of some obscure WM syntax
-Automatically finds icons
-Caches icons for speed
How do I install it?
| Code: |
$ emerge pygtk pyxdg
|
Then copy and paste the pymenu.py script and the showpymenu script below and put them wherever you like, maybe in ~/pymenu. Put:
| Code: |
python ~/pymenu/pymenu.py
|
In your .xsession file, or your wm's startup file. PyMenu will start when your wm starts and run in the background. Then, use whatever is normal for your wm to bind a key or a mouse click to the showpymenu script, which will cause pymenu to appear.
Now, to actually have stuff appear in the menu, by default, pymenu will look in ~/.pymenu/menu for symlinks. Go ahead and make this folder. Then make subfolders and fill them with symlinks. For example, to add tuxracer to the menu:
| Code: |
$ cd ~/.pymenu/menu
$ mkdir Games
$ cd Games
$ ln -s /usr/bin/tuxracer TuxRacer
|
Now open PyMenu with the bind you have setup, and click "Refresh Menu." TuxRacer should appear
I have a specific icon I want PyMenu to use, how can I make it use it?
PyMenu will always look for icons in your ~/.icons folder first. Put the icons you want there.
PyMenu isn't finding my icons, why?
First, make sure if you have specific icons you want that they are in ~/.icons. PyMenu will search other locations, such as /usr/share/pixmaps, after that.
Also, pymenu expects the name of the icon file to correspond to the name of the executable for a program. For The GIMP for example, it will search for gimp-2.0.png, not gimp.png.
I'm using sawfish, and the menu isn't appearing!
Sawfish has some quirky behavior with keybinds that can cause the menu not to appear. Put this in your .sawfishrc to bind right mouse click on the root window to showing the menu:
| Code: |
(defun showPyMenu ()
(ungrab-pointer)
(ungrab-keyboard)
(ungrab-server)
(sync-server t)
(signal-process (string->number (read-line (open-file "~/.pymenu/.pid" `read))) 10))
(bind-keys root-window-keymap
"Button3-Click" `(showPyMenu))
|
This workaround isn't perfect, you'll have to hold the button down in order for the menu to stay visible.
The menu won't appear
Run:
| Code: |
$ ps aux | grep pymenu
|
And make sure that pymenu is running. If it is not you haven't set it up to startup with your wm properly. Also, make sure you have chmod'd the showpymenu script to be executable:
| Code: |
$ chmod +x showpymenu
|
Where did you get the icons in the screenshot?
They were made by the Gentoo community: http://www.gentoo.org/dyn/icons.xml
If I want to submit patches where should I send them?
k 0 4 j g 0 2 {(a)(t)} k z o o {(d)(o)(t)} e d u
Or just post them here!
Alright already! Where's the code?

Wait, what's this MODULE_FOLDER setting?
My original plan was to clean up the code a lot and make PyMenu easily extendable with modules. But spring break is just about over so I don't have the time right now. Feel free to submit patches though 
Stuff I wish I had time to add:
-Support for .directory files
-Support for freedesktop.org menu format
-Module extendability
-Keyboard shortcut support (preferably autogenerated, like icon finding)
-Rewrite icon finding code to use find shell command for speed
-Dialogs to configure without command line
-Ebuild

Hopefully, if I get the time to rewrite it, with modules people will be able to add fluxbox's menu options to PyMenu.
Also, if anyone wants to use their WMs old menu and this one, just bind them to separate clicks. For example, I use sawfish, but I still find myself needing stuff from the normal sawfish menu, so I have it bound to mouse button3 and PyMenu bound to mouse button2. |

PyMenu looks in ~/.pymenu/menu by default. The structure of the folders there determines what the menu will look like. For example if you have the folders:
~/.pymenu/menu/Games
~/.pymenu/menu/Adventure
~/.pymenu/menu/Internet
Then you'll see 3 subfolders in the menu, Games, Adventure, and Internet. There can also be folders within folders.
Also, the way you put items in a folder, is to make a symlink to the app you want inside the folder. See the example in the first post for adding Tuxracer to the menu to get the idea.
The actual menu used by the app is not stored per se, it's generated on the fly by what's inside ~/.pymenu/menu. But that's only the default, if you edit ~/.pymenu/.pymenurc you can make it represent any arbitrary folder you like. |
